I should also add with regard to lens hood use on a tele-zoom . . .
In a long prime, the rear element is typically well forward of the lens
mounting flange and there are light baffles between the rear element and
lens mount . . . which should make it less prone to certain types of
off-axis flare.
Unlike long primes, the rear element of a tele-zoom is usually at or very
near the lens mount leaving no room for any light baffles. In the case of
this specific 80-200/2.8 Tamron, the rear element doesn't move and it's
right at the lens mount.
